In the stone house, Lin Chenyi was excited to see that in the list of goods, the Burial Soul Bead was impressively listed, there were no restrictions on sales, and there were three thousand left!

Each Soul Burial Bead is not cheap, it requires as much as five hundred blood qi points, but for Lin Chenyi, a local tyrant with a huge wealth, there is no pressure at all!

Without hesitation, Lin Chenyi swept away all the Soul Beads in the Black Sand Secret Realm Store, spending a total of 1.5 million blood qi points.

Then a hole appeared on the stone table, and a large number of orange-red beads poured out of the hole, as if popcorn burst out of a pot, and Lin Chenyi was a little refreshed.

Lin Chenyi put all these burial soul beads into the storage ring, leaving only one in his hand, he had never touched the burial soul beads, so he couldn't help but observe curiously.

I don't know how these soul beads were formed, each one is full and round, like a pearl, the size of a lychee, the texture is silky, with the help of the light in the room, the beads are glowing with an orange-red clear luster, as if there is a red liquid flowing inside.

With the Burial Soul Orb, the next step is, of course, to loot the limited treasures of the secret store here.

For example, the price of purple god jade is only 399 pieces/ton, which is so cheap!

I don't know who was too expensive before, at this time, Lin Chenyi swept away all the most precious treasures on the list, and he didn't even blink his eyes, including 3 tons of purple god jade, 1 ton of three-eyed gold stone, and 2 tons of red fire copper.

These rare metals all appeared through the holes in the stone table, and there were a lot of impurities on each piece of metal, just as Lin Chenyi guessed.

Putting away these rare metals, Lin Chenyi had the idea of striking the sky again.

He consumed 2,596 Burial Soul Beads just now, which was naturally not enough to buy Eagle Strike Changkong, but the black sand ants outside had enough Burial Soul Beads!

Is he really helpless against the black sand ants outside, not necessarily!

He was not familiar with the black sand ants before, and he was afraid of the terrifying number of black sand ants, so he had to take everyone to hide in the secret store.

But after the battle just now, summing up the combat experience, I found that the black sand ant is not without shortcomings!

The Black Sand Ant's defense is certainly strong, and it also has the perverted attribute of devouring spiritual energy, but what if you use gunpowder?

Coincidentally, there are a lot of Xingchen flints in Liuyun Immortal Mansion, originally these Xingchen flints were one of the gunpowder used to make Chenxing's special bullets, which were of good quality and cheap, a ton of Xingchen flint was only a dozen points of blood and gas value, and the best quality ones were less than fifty points of blood and gas value, so the monkeys hoarded a lot.

If these Star Flint Stones are used properly, they can produce as much power as real TNT, which is much more cost-effective than throwing amethysts or using the Hanhai Divine Needle, and the risk is almost zero.

Those black sand ants devouring attributes are no longer hanging, and they can't devour the energy of pure gunpowder such as Xingchen Flint after the chemical reaction, so don't play like this.

So, Lin Chenyi left the stone house and told everyone about this idea, and the monkey who was familiar with the holy water bottle immediately agreed:

"Boss, why didn't I think of this idea, the technology for making explosives is in the Holy Water Bottle skill, and I suggest we use this method more in the future!"

Lin Chenyi said: "Oh, why? ”

The monkey said triumphantly: "Whether it is the star flint or other gunpowder with different powers, their biggest feature is that they do not have any spiritual power fluctuations.

Although the strong are very sensitive to spiritual power fluctuations, others are not, even when they feel danger, it is also the time for the release of gunpowder energy into the explosion, and if we use it well, we can still kill some enemies. ”

Lin Chenyi was stunned, isn't it, before the gunpowder reacts, at most it is a lump without energy fluctuations, and the spiritual survey of the strong cannot detect it at all, or if it is detected, it does not care, because there is no relevant experience in dealing with it at all.

It seems that cultivators are not really without flaws, at least modern thermal weapons and the like, if they are unprepared, can also cause devastating damage to cultivators.

Because of this, he strictly controls Chenxing and its bullet technology to avoid leakage of related technology, which will lead to any changes, which is not a joke.

Just imagine what a terrible thing it would be to be controlled by a cultivator with a hot weapon, especially in this plane where there is no sense of the legal system, I am afraid it will be a disaster for all living beings!

Putting aside his thoughts, Lin Chenyi mobilized everyone to return to Liuyun Immortal Mansion and hurry up to make a batch of explosives.

However, when it came to the hands-on operation, there was a disagreement on the plan for making explosives.

Lin Chenyi proposed to throw the explosive bag directly and detonate the explosive bag through the Hong Huang Seal.

This has the advantage of maximizing the lethality of the ground, and the black sand ants under the flood and desolation have absolutely no way to live.

However, the monkey objected: "Boss, your plan is flawed, we killed the black sand ants to relieve the siege, but more to bury the soul beads."

Let's not talk about whether the Soul Bead can withstand a local explosion under oppression, just after killing the Black Sand Ant, we dig up the Soul Bead is a huge project, right? ”

Lin Chenyi nodded and said, "This is my negligence, but if you don't do this, how can you detonate the explosives?" ”

The monkey smiled: "This is simple, don't we have the drawings of the concentrating magic cannon, let's modify it a little, change it to an earthen cannon structure, with a built-in high-strength spring, make the explosives into round shells, release them through ejection, and set up a firing pin in the cannonball, and detonate the explosives inside through a violent impact!" ”

The monkey said it as bluntly as possible, although Lin Chenyi didn't understand the professional knowledge of the military industry, he still understood.

Moreover, this spring setting is obviously the monkey's creativity, after all, with the current environment, it is not possible to make good artillery and cannonballs, it is better to shoot the cannonballs through the spring, which is simple and rude.

At the same time, this spring can also adjust the projection distance of the cannonball, with the physique of all of them, they can manually compress the spring to the extreme, and the range should be said to be very impressive.

Hundreds of goblins moved by the monkeys, working together, some designing barrels, some springs, some shells, and some measuring the correlation between the compression of springs and the range distance.

Although Lin Chenyi didn't understand these, he could still see the terrifying and efficient R&D capabilities of the goblin team, and everything was like a cloud of peers, which made people very comfortable to watch.

About half an hour later, the first earthen cannon was successfully developed by the goblin, and Lin Chenyi's first feeling when he saw this earthen cannon was that it was too long and too thick!

That's right, this earthen cannon can only be described as shoddy, the whole is very bulky, the barrel alone is three meters long, and one and a half meters of it are firing devices, that is, the spring is more than one meter long!!

The diameter of the muzzle is also half a meter, which is much more terrifying than the caliber of those real guns.

Of course, the reason why this muzzle caliber is large is because it is necessary to put in a large enough cannonball, and the monkeys also added a lifting device to the barrel, and made six wheels underneath to propel, which looks like a crane without a front of the car.
